^4. //. Curtiss, no. 1195* (t}^e, in Gray Herb.); Key West, Blodgett; 

 Jew Fish Key, Chapman; rich thicket, Key Largo, June, 1880, A. H. 

 Curtiss, no. 171 ; Upper Metacumbe, 11 April, 1892, J. H. Simpson, no. 

 565. This species, long identified with the Jamaican E. heteroclinium 

 Griseb., differs in having decidedly smaller heads, shorter leaves of a 

 more deltoid contour, more obtuse involucral scales, olivaceous instead 

 of dark violet-brown achenes which are strigillose instead of smooth on 

 their faces, and in other minor characters. Were these plants of 

 Florida and Jamaica really identical, it would certainly be strange that 

 their range did not include Cuba. 



EuPATORiUM GLABRATUM HBK. Nov. Gen. et Spec. iv. 127 (1820). 

 To the synonymy of this species should be added E. xalapense HBK. 1. c. 

 128 (1820), and E. gonocladum DC. Prod. v. 171 (1836). The greater 

 part of recently collected material of this affinity has been referred to E. 

 glahratum, while E. xalapense and E. gonocladum have remained ob- 

 scure. After examining at the herbarium of the Museum of Natural 

 History in Paris original material of E. glahratum and E. xalapense, 

 and at the De Candollean herbarium in Geneva the exceedingly frag- 

 mentary type of E. gonocladum, the writer has failed to detect any sig- 

 nificant difference. Of the two earlier names, the more commonly used 

 E. glahratum happily has priority of position.
